- a THE LIKE Application filed June, 9, 1931,

This invention relates more particularly, to a class of perforating and threading devices for stoppers, faucets, and the like implements, mountable at any convenient part of the body, of sheet-material, or metal containers, by completely, or partially shearing out a circular portion thereof, when the device is driven through the sheet body of a container, and to screw through the perforated body portion, whenthe device is rotated. I l

The main object of the invention is the provision of a device as above, for perforating and screwing through the sheet-material, or

metal body of a container, in a positivized manner, so that the outlet and operative parts of a dispensing device associated therewith, may be caused to assume a predetermined fastened position relative the body, end-walls, or cap of a container.

Other objects will be scription proceeds. I p

combined with a measuring and dispensing stopper 2, which is embodied in my Patent N 0. 1,560,013, issued to me, Nov. 3,1925. Said stopper, therefore, is in part-described only for illustrating a combination for the present invention, in which, the threaded annular flange of the stopper, has been modified to a reduced tubular portion 3, extending perpendicularly, from the circular top plate of thestopper, which is being referred to as annular shoulder 4. Device 1 may be made integral with portion 3 of the stopper, though as shown, it is made from a suitable sheet metal blank 5, Fig. 5, having a substantially V-shaped portion 6, with a cutting edge 7, and a pointed end 8. On-the blank is also a rectangular portion 9, with rivet-bores 10. Said blank is rolled or stamped to a tubular form, as shown in Fig. 1. 'Encircling'the tubular surface of portion 9 is an exteriorly projecting screw-thread 11, with its end, turn closed by shoulder 4. The inlet end ofsaid thread hasan oblique or downwardly bent portion with a pointed end 12 parallel to the axis of the cylinder of the body and intersecting the upper portion of edge 7, as more clearly seen in Fig- 3. Said "perforating. and threading device may be variously fastenedon said stopper, though as shown, I secureit with its portion 9 encircling said portion 3, by means of rivets 13, inserted from bores '14, formed at the cylindrical wall of portion 3in similar fashion, as bores 14A, Fig. 8, thence thru bores 10 of the device and-headed thereabove, as at F ig. 3. J

g. 6, may be worked-up similarly as blank 5 Just described, though as obin this form of blank, the perforating and threading device will contain two diametrically opposed perforating portions 6.

The type of faucet 15, shown in Fig. 7, is of an ordinary construction having a reduced portion, or shank,.and an annular shoulder 16, against which, similar to the stopper shown in Figs. 1, 2 and 3, may abut a suitable washer, or gasket 17. And at the reduced end of the faucet, may be integrally formed, or fastened, a'similar perforating device as described hereabove. The same applies withthe plug element 18, Fig. 8, which has a top wall 19, bearing a handle 20, from which it is manipulated. Whereas, in the case of both the stopper and faucet, their upper body portions act as handles from which this perforating and threading device may be conveniently manipulated.

Although the operation of the device is already obvious in the above description, I will now outline one mode of its operation in conjunction with the stopper.

In attaching, or mounting said stopper on the cylindrical wall of a can, or container 21, having a cover 22 which in this instance, is not necessary tobe removed, the container is placed in an horizontal position as at Fig. 1, and piercing point 8 is inserted thru the cylindrical wall in close proximity to bottom 23, so that handle 2A of the stopper fronts cover 22. Portion 6 of the perforating device is completely driven perpendicularly thru said wall without rotating the same, until point 12 has penetrated also. And assuming thread 11 to be one turn, half of which residing within washer, or gasket 17 by rotating the device until handle 2A is perpendicular with bottom 23, the device will have assumed its convenient operative dispensing position and be fastened on the can, as at Figs. 2 and 3. During said operation, a circular portion 24 will be partly severed and bent inwardly of the can and out of the path of the interior of the tubular cutter, leaving an unsevered portion 25, as at Fig. 4, which is simultaneously engaged by the inlet portion and pointed end 12 of the thread in which a tear, or notch 26 is produced which expands diametrically that portion of perforation 27 in which the thread begins to act, guided by point 12, in threading with a larger diametrical portion than the marginal diameter of said circular perforation, resulting in a consistent mounting for said stopper, or the like implements which may be associated with said perforating and threading device.

While in the above I have limited the description of the device as being made from "flat metal stock, it is obvious, thatI may employ tubing-stock instead. And in either metal stocks, I may form said device with a fastening flange, or serrated flange, as in dotted illustration 28 Fig. 5, from which it may be fastened directly at the annular shoulder of any said implements in any suitable manner. For example, I may form the said stopper, in a light metal stamped construction retaining its original flanged cap, insert device 1, formed with flange 28 interiorly of said cap and then turn in the flange of the cap against the serrated flange of the device "unrotatably joining the same.

In the foregoing description, I have embodied the preferred formof my invention,

but I do not wish to be understood as limiting myself thereto, as I am aware that modi-' fications may be made therein without de parting from the principle or sacrificing any of the advantages of this invention, therefore, I reserve to myself the right to make such changes as fairly fall within the scope of the claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In combination with a device of the class described, having a tubular body with a bevel or diagonal cutting edge with a pointed end to pierce sheet material or metal and having an exteriorly projecting screwthreaded portion, of a downwardly. bent thread portion at the inlet turn of the thread perpendicular with the surface of the body to guide said thread thru perforated sheet material or metal.
